A VAV terminal unit, often called a VAV box, is a zone-level flow control device. It is a calibrated air damper with an automatic actuator. The VAV terminal unit is connected to either a local or a central control system. Historically, pneumatic control was commonplace, but electronic direct digital control systems are popular especially for mid-to-large size applications. Hybrid control, for example having pneumatic actuators with digital data collection, is popular as well.

The square diffuser with plenum box is designed to disperse incoming air throughout a room or space.
